Update: I see some commenters here think this is a non-story. Fair enough.

But I would draw your attention to this, in which Mr Cameron proclaims that "Swearing in public, neglecting the elderly, being rude to shop workers or bus drivers — these should be as unacceptable as racism".

Now, call me old fashioned, but I think it's my job to point out cases where there may be a difference between what politicians do and what they say.
